Sipper tube cap assembly

Abstract

A sipper tube cap assembly is provided having a cap with a flat surface and a curved wall. A circumferential flange is formed by the flat surface and further defines an opening in the cap. A stopper, having a hole formed therein, is positioned in said cap by said circumferential flange to retain the stopper within the cap. Finally, a sipper tube is provided which is positioned within the hole in the stopper, to extend through the opening.

What is claimed is: 
     
       1. A sipper tube cap assembly, comprising: a cap having a curved side wall having an inner surface and an outer surface;   a circumferential flange extending from said curved side wall and defining an opening in said cap;   a stopper dimensioned to seal said opening, said stopper having a hole therein, said stopper being maintained in said cap by said circumferential flange, said stopper including a first lip, a second lip and a neck positioned between said first and second lips and disposed within said opening, said neck and said second lip each having a diameter, the opening having a diameter less than said neck and said diameter of said first lip being at least as great as the diameter of said circumferential flange; and   a sipper tube adapted to be positioned within said hole and extending through said opening.   
     
     
       2. The assembly of claim 1, wherein said second lip further comprises a sloped surface. 
     
     
       3. The assembly of claim 1, wherein said stopper further comprises a channel formed in said first lip. 
     
     
       4. The assembly of claim 3, wherein said channel is dimensioned to receive a top edge of a bottle to form a substantially tight seal therebetween. 
     
     
       5. The assembly of claim 3, wherein said channel extends to an outer periphery of said first lip. 
     
     
       6. The assembly of claim 5, wherein said channel is dimensioned to receive a top edge of a bottle to form a substantially tight seal therebetween. 
     
     
       7. The assembly of claim 1, wherein said stopper is formed of a malleable pliant material. 
     
     
       8. The assembly of claim 1, further comprising serrations formed on said outer surface of said curved wall. 
     
     
       9. The assembly of claim 1, further comprising a thread formed on said inner surface of said curved wall. 
     
     
       10. A method for assembling a sipper tube cap assembly, comprising the steps of: forming a cap having a curved side wall having an inner surface and an outer surface and a circumferential flange extending from said curved side wall and defining an opening in said cap;   forming a stopper dimensioned to seal said opening having a hole therein, said stopper being maintained in said cap by said circumferential flange, forming said stopper with a first lip, a second lip and a neck positioned between said first and second lips, said neck having a diameter, the opening having a diameter less than the diameter of said neck and said first lip having a diameter extending to said sidewall; and   inserting said stopper into said opening of said cap;   positioning said neck within said opening;   positioning a sipper tube within said hole and extending through said opening.
